In this report you'll learn how we're protecting public health, our drinking water supply and the environment for future generations to come.
Our actions demonstrate a strong commitment to the environmental management and sustainability of the North Saskatchewan River, including these highlights from 2015:
Highlights of 2015 EnviroVista Initiatives:
- Achieved ISO14001 registration early in 2015 for the Environmental Management System for the Edmonton Drinking Water Treatment Plants and completed almost a full year of operation under the management system;
- Reviewed and updated the Drinking Water Safety Plan, addressed five risks, and added several new action plans to address other risks;
- Began the development of a Geographical Response plan with Alberta Environment and Parks to help address the risks of source water contamination via a spill to the river upstream of Edmonton;
Achieved total per capita water use of 288 litres per person per day (L/p/d). This is well below the Alberta Urban Municipality Association (AUMA) water use target of 341 L/p/d by 2020;
- Achieved the lowest level of water loss in the distribution system with an all-time low infrastructure leakage index of 1.14. The industry bench mark is to be less than 3.0;
- Completed a field study to help optimize the frequency of unidirectional flushing (UDF) of water mains. Optimizing UDF will reduce the amount of water losses in the system;
- Further reduced the energy consumed to pump and distribute water on a kWh per ML basis throughout the system compared to 2014 and exceeded the performance benchmark of 670 kWh/ML for overall system energy performance;
- Completed construction of a new Water Laboratory facility at the Rossdale site and renewed accreditation of the lab to ISO/IEC17025 for the new facility;
- Continued to fund a research project with the City of Calgary on sustainable urban water management;
- Achieved a 43 per cent reduction in the water treatment plant solids discharged to the river during winter and fall months converting to direct filtration operation; and
- Tested a datasonde instrument to collect better information on the localized impact of releases from the water treatment plants to the North Saskatchewan River.
